Claims (12)

  1. Kurbelgehäusegespülter Zweitaktverbrennungsmotor (1) mit einer zusätzlichen Luftzufuhr (2), die an seinen Überführungsleitungen (3) angeordnet ist, wobei die Überführungsleitungen (3) ein Kurbelgehäusevolumen (4) und einen Überführungsdurchlass (5) verbinden und die zusätzliche Luftzufuhr (2) zu den Überführungsleitungen (3) über eine Luftleitung (21), welche mit dem Zylinder (9) verbunden ist, und über die Zylinderwand (29) angeordnet ist, welche zu einem Luftzufuhrdurchlass (22) führt, der über einen Aussparung (24) in einem Kolben (7) für bestimmte Kolbenpositionen mit dem Übertragungsdurchlass (5) verbunden ist, dadurch gekennzeichnet, dass zumindest eine Aussparung (6, 24) im Kolben (7) vorliegt, die unterhalb eines Kolbenrings (10, 11) angeordnet ist, und ferner ein Stromkanal (12) vorliegt, der die Aussparung (6; 24) und das Kurbelgehäusevolumen (4) verbindet, wobei der Stromkanal (12) alternativ außerdem als die Aussparung (6) fungiert, und der Stromkanal (12) im Kolben (7) angeordnet ist und die Aussparung (6; 24), oder der Stromkanal (12), falls der Stromkanal (12) als die Aussparung (6) fungiert, zum Zusammenpassen mit dem Überführungsdurchlass (5) für bestimmte Kolbenpositionen zum Schaffen einer Verbindung zwischen dem Überführungsdurchlass (5) und dem Kurbelgehäusevolumen (4) über den Stromkanal (12) angeordnet ist.
  2. Kurbelgehäusegespülter Zweitaktverbrennungsmotor (1) mit einer zusätzlichen Luftzufuhr (2), die an seinen Überführungsleitungen (3) angeordnet ist, wobei die Überführungsleitungen (3) ein Kurbelgehäusevolumen (4) und einen Überführungsdurchlass (5) verbinden und die zusätzliche Luftzufuhr (2) zu den Überführungsleitungen (3) über eine Luftleitung (21), welche mit dem Zylinder (9) verbunden ist, und über die Zylinderwand (29) angeordnet ist, welche zu einem Luftzufuhrdurchlass (22) führt, der über einen Aussparung (24) in einem Kolben (7) für bestimmte Kolbenpositionen mit dem Übertragungsdurchlass (5) verbunden ist, dadurch gekennzeichnet, dass zumindest eine Aussparung (6, 24) im Kolben (7) vorliegt, die unterhalb eines Kolbenrings (10, 11) angeordnet ist, und ferner ein Stromkanal (13) in Verbindung mit dem Kurbelgehäusevolumen (4) vorliegt, der in einer Zylinderwand (29) des Motorzylinders (9) angeordnet ist, und die Aussparung (6, 24) zum Zusammenpassen mit dem Stromkanal (13) sowie dem Überführungsdurchlass für bestimmte Kolbenpositionen zum Schaffen einer Verbindung zwischen dem Überführungsdurchlass (5) und dem Kurbelgehäusevolumen (4) über den Stromkanal (12) angeordnet ist, wobei die zumindest eine Aussparung (6, 24), wenn sich der Kolben (7) von der unteren Totpunktposition anhebt, zuerst den Überführungsdurchlass (5) über den Stromkanal (13) mit dem Kurbelgehäusevolumen (4) verbindet und danach den Überführungsdurchlass (5) mit der Luftleitung (21) verbindet.
